Fig. 4 is asecnot herein shown, but which will in practice be used in this improved loom, being therein fully shown and described, like letters and numerals being used. The pattern-surface surrounds a pattern-shaft h having at its inner end a ratchet-wheel h, which is engaged by a pawl h, pivoted on a pawl-carrier h, having an attached rod h jointed to the end of an elbow-lever 7L8, having its pivot on a shaft 7L and provided at its upper end with a catch h having a shoulder h, which will be herein furtherdescribed when defining the invention herein contained. The lever its is normally held toward its actuating-cam h by a spring 71 connected to it and to a lever It, also pivoted at ]L9 and moved by a cam 126, said lever it having a slip connection 71, which engages a pin h on the lever h but whenever the catch h is permitted to engage a shoulder of a slide-bar 401, to be described, the movement of the lever 72, and the pattern-surface for the shuttle-box mechanism is stopped and the cam It continues to rotate, the lever 71 then moving and the slip device 72. then slipping on the pin h thus preventing the breaking of the parts and allowing the pattern surface to stand still. These devices for moving the pattern-surface are substantially found in United States Patent No. 364,696, dated June 14, 1887. The stopping of the pattern-surface is efiected preparatory to operating the transferrer 26, to be described, so that the pattern-surface will remain in proper relation to the other working parts.

The frame of the loom is provided with suitable brackets G, which receive a rock-shaft G, having two arms G2 G the arm G being connected by a link G4 with the shuttle-box lever E. The arm G of the rock-shaft has connected to it a rack-bar G the said link, rock-shaft, arms, and rack constituting means for actuating the system of gearing for moving the filling-carrier feeder G backward and forward in unison with the rising and falling movements of the shuttle-box.

The filling-feeder G, as herein represented, (see Fig. 10, where the same is shown detached,) consists of a substantially circular cage composed of a hollow hub G provided at one end with a circular head 20, having extended horizontally from it parallel to said hub a series of arms or fins 25, said arms or fins at their ends farthest from said head being connected to and support-ing a toothed ring 24. The hollow hub G of the fillingfeeder is supported on a stud G extended horizontally from one side of a stand G fixed on the breast-beam A of the loom-frame, the said hub being prolonged outside the head 20 by a second sleeve G connected to the outer side of said head, and to the said sleeve G is connected a filling end support G and a filling end holder G the filling-feeder being kept on the said stud by a suitable bolt G (See Fig. 1.) The head 20 of the filling-feeder has a series of radial notches, in which are located suitable springs 21, one for each notch,

ferrer 26, to be hereinafter described, may

enter and be moved freely therein, said transferrer when made to descend striking the filling-carrier 22 then under it and ejecting said filling-carrier from the feeder into the shuttle 27 then in the shuttle-box below the feeder, this action taking place whenever the yarn has been nearly exhausted from the fillingcarrier then in the shuttle, but only after such shuttle has arrived in the shuttle-box 27 which is located under the said feeder, said shuttle-box being fixed to that end of the lay farthest from the shifting shuttle-boxes.

The shuttle 27, Fig. 11, is of that variety wherein there is a passage through it from one side to the other side in order that the filling-carrier put into it at one side may be ejected from it at the opposite side, the said shuttle having suitable filling-carrier holders 28 of such shape as to receive rings or projections 29 of the filling-carriers 22, the shuttle also having a self or automatic threading contrivance comprehending a slot (Z and a horn 30, (see Fig. 11,) which may be of any of the usual forms of construction, so that when a filling-carrier in the filling-carrier feeder (said filling-carrier having the end of its thread connected with the holder G is put by the transferrer into the shuttlethat movement ejecting the filling-carrier thenin the shuttle through the shuttle and out from the bottom of the lay--the thread of said filling-carrier as the shuttle is thrown through the shed will be automatically threaded into the slot CF and delivery-eye c1 of the selfthreading contrivance of the shuttle, so that the shuttle will correctly deliver the filling from it into the shed.

The filling-feeder herein described and the transferrer and the shuttle having the selfthreading contrivance are in operation substantially the same as described in certain United States Patents, granted to James H. Northrop, No. 529,9l0, and G. O. Draper, No. 538,507; but in order to enable a shiftingshuttle-box loom to have its shuttles carrying filling of different character or colors to be automatically supplied with filling-carriers having yarn of the proper character or color thesaid filling-feeder has imparted to it two difierent sets of movements, one aiming to keep in working position or above the shuttle in operation a filling-carrier of the same color, the other movement coming into play only after the removal of a filling-carrier from the feeder into the shuttle, the movement being to skip to the next group of filling-carriers and put in operative position with rela- ICS tion to the shuttle another group of fillingcarriers supplied with all the colors of filling being used, putting a filling of the desired character or .color just removed from one group into operative position with relation to the shuttle then in use. The filling-carriers are arranged in the filling-feeder in groups, and inasmuch as in this invention the shifting shuttle-box is provided filling of-the colors red and white.

The teeth of the toothed ring 24 of the 'filling-feeder are engaged by the. teeth of a gear 31, mounted looselyon a stud 32 in a stand 31 the said gear having, however, peculiar movements, as we will now describe.

The gear 31 has connected to ita stud 33, on which is loosely mounted a bevel-pinion 34, the said bevel-pinion being engaged by the bevel-teeth of a gear 35, loose on the stud 32 andengaged by the teeth of the rack G before described, said bevel-pinion 34 also engaging the bevel-teeth of and moving a gear 36, also loose on said stud 32, the bevel-pinion 34 connecting the said two gears 35 and 36. The teeth of the loosegear 36are in mesh with a gear 32 mounted on the stud 36 having an attached ratchet-wheel 333, which may be moved intermittingly in one direction only by a pawl 34 The gear 31 may therefore be moved from two sources'that is, it may be oscillated by the rack G gear 35, and bevel-pinion 34, the gear 36'being then held fast, or it may be rotated from the gear 32 as will be described, the rack and gear 35 being then held fast by the wheel 32 The pawl 34 is attached to a pawl-carrier 35 mounted on the stud 36, the pawl-carrier having connected to its lower end a rod 37, attached to a lever 38, having its fulcrum at 39 and acted upon by a cam 40 on the lower cam-shaft B, the said pawl thus having a constant motion; but the pawl cannotengagethe ratchet-wheel except when a filling-carrier is to be ejected from a shuttle and a new one put into the shuttle. i 1

Let it be'supposed that a shuttle-box havinga red filling is in position at the level of the race of the lay and is working, and in such position the red filling in a group of fillingcarriers is stopped immediately below theend of the transferrer, and so long as that red filling goes in and the shuttle-boxes are not shifted the red-filling carrier stands in that position and'the rack G stands still; but if the next shuttle fromthe redfilling sh'uttle viz., the one containing white-should be brought into position by shifting the sh uttlebox lever in usual manner, then that movement of the shuttle-box lever through the operative mechanism connecting it with the rack G moves the said rack and effects the turning of the filling-feeder far enough to bring the white carrier in position below the transferrer. It will consequently be understood that the filing-feeder has an oscillating motion inextent dependent uponthemotion of the shifting shuttle-boxes, and whatever the movement of the shuttle-boxes the filling-feeder has a corresponding movement, so as to always preserve the proper relative arrangement of colors, and when a measured quantity of the yarn on a filling-carrier then in use has been measured off, as will be hereinafter described, the transferrer will'be operated, as will be described, and it will descend and take from the filling-feeder a filling-carrier having a filling of a color correspon'ding with that in. the shuttle in which new filling is to be placed and then thereafter comes in the new or second movement of the filling-fieeder. One filling-carrier having been exhausted from a groupof filling-carriers, another group of filling-carriers must be, instantly brought into position wherein all the colors are represented in order that should the same color be next required to be taken from the filling-carrier feeder there would be opposite the transferrer a fillingcarrier having filling of the proper color.

The second motion referred to herein described is one of progressive rotation, and to effect this for the proper distance the pawl 34 is let come into play in the following manner, viz: The outer end of the pawl 34 (see Figs. 4 and 13,) attached to the elbow-lever 35 pivoted on the stud 36 lies normally on and is reciprocated backward and forwardover a pawl-lifter 41 and a pawl-rest 40 but normally the pawl is not moved off from the said rest andit cannot consequently engage the teeth of the ratchet 33 to turn it. The pawllifter 41 is pivotally mounted upon the pawlrest 40 shown as a second elbow lever mounted upon the stud 36* outside the lever 35 one arm of said pawl rest being shown as provided with an adjustable stud 42, which is embraced by the slotted end of a pawl-rest controller 43, shown as a lever having its fulcrum on a stud 44,.projected from the stand G the opposite end of said controller being also shown as forked (see Fig.

4) and as embracing apin 45, carried by the v support its acting end or portion which acts on the filling-carriers above the said carriers. The stud 47 has wound upon it a suitable strong spiral spring 48, the free end of which engages the transferrer-carrying arm, while the opposite end of said spring is fixed with relation to the stud, the said spring normally keeping the transferrer elevated, so that the filling-carriers held in the feeder in the move- 'shown by dotted lines.

ment of the latter may readily pass under the acting end of the transferre'r. The transferrer has a short arm 26 (see Fig. 4) and the lay-beam has an attached bunter H and whenever a finger H attached to a sliding and rocking rod H, to be herein further described, having suitable bearings under the breast-beam, is moved, in this instance of our invention to the right, Fig. 1, far enough to put said finger in the path of the short arm 26 of the transferrer and the hunter the lay as it comes forward causes the bunter to act on the finger and give the latter a quick movement, causing the finger to act on the arm 26 and move the transferrer-carrying arm, so that it will act on and take the filling-carrier then under it from the filling-feeder and put it into the shuttle then in the stationary box, the incoming filling-carrier meeting and ejecting from the shuttle the filling-carrier therein from which the yarn has been nearly all measured off. In order that the gear 32 may not be moved farther than required, a suitable spring-pressed locking-lever 49 (see Fig. 4) has been provided, it having a roll (shown in that figure by dotted lines) which enters notches in a notched wheel 50, also While the transferrer is descending to act upon and remove a filling-carrier from the filling-feeder, the lever 43 is moved sufficiently to turn the pawlrest 40 a little to the right, so that as the pawl 3? is again moved forward it slips over the end of the said rest, drops into engagement with a tooth of the ratchet-wheel 33 and gives it a quick movement, the said movement taking place, however, after the transferrer has effected its work, the movement being sufficient to move the filling-feeder for a distance equal to the space occupied by one group of filling, so that a filling-carrier of the same color may be brought into operative position under the transferrer after a fillingearrier has been ejected from the feeder, or, in other words, the filling-carrier which is brought by the movement of the feeder, due to the ratchet referred to, in position opposite the transferrer will always be of the same color as that on the filling-carrier which was just removed from the feeder by the transferrer.

In practice the gears 36 and 32? will be in such proportion as to size and the ratchetteeth of the gear 32 will be in such number as to give to the filling-feeder the desired extent of movement, that depending upon the number of colors used in the filling-feeder and the number of shuttle-boxes employed at the opposite end of the loom. This proportion may be varied at will according to the number of colors and the work to be done. The pawl 3l having reached the end of its back stroke, it having moved the ratchet, again starts forward in the regular movement of the pawl, and the finger projecting from the pawl strikes the free end of the pivoted pawl-lifter 41 said end being downturned,

so that it catches under and lifts the pawl from engagement with the ratchet and enables it to slide back and forth on the pawlrest 40 until the transferrer is again operated.

In this invention the movement of the transferrer is dependent upon, as herein shown, the removal of a measured quantity of filling from a filling-carrier.

The filling-fork 50 herein used to stop the loom when the filling breaks, is pivoted at 51 on a slide 52, whiehis adapted to be reciprocated in a stand 53, fixed to the breastbeam A,the filling-fork having at its inner end the usual heel, (shown by dotted lines, Fig. 4,) which drops whenever the filling is absent from in front of the filling-fork as the lay beats forward, so that said heel is caught by the upper end of the filling-hammer 55. This hammer is shown as a lever pivoted at 56 and having an arm 57, which is acted upon by a suitable cam 58 on the shaft 13, all in usual manner.

Any other usual form of self-threading shuttle, of which there are many examples, may be employed.

We have mentioned that the fillings are of different colors; but they may be of different material or character, each one working in its own proper shuttle in a defined order.

The system of gearing herein shown to impart the described movements to the feeder is one form of epicycloidal gearing, and instead any other usual or equivalent means may be employed to actuate the feeder.

The open ring-like inner end of the fillingfeeder, having the teeth to be engaged by the pinion 31, is supported by arms or fins 25; but all the said fins are not needed, and it is not essential to separate the filling-carriers at any particular spot.

The lever E, controlled by the patternchains 0 determines by its movement not only the position of a shuttle having filling of a particular color, but it also determines independently by or through the shaft G the particular color of the filling on the fillingcarriers to stand under the pusher.

The parts so far described are contained in another application for United States patent, said application having the Serial No. 597,975, filed July 3, 1896, and are not therefore herein broadly claimed.

In order that a filling-carrier in a shuttle being used may be withdrawn from operation after a stated length of filling has been taken from the filling-carrier,measuring means have been devised for measuring the filling as used, which means will now be described. This measuring means, as it has been chosen to herein illustrate it, consists, essentially, of two ratchet-wheels 201 and 202, (see Figs. 8 and 9,) the one 201 having twenty-one teeth and the one 202 alongside of it having twenty teeth, the said ratchet-wheels being mounted on a stud 250 and both actuated by the same pawl 203, attached to an arm 210 (see dotted lines Fig. 3) of the rock-shaft h", constituting the pivot for the levers h and h, said rockshaft having a second arm 213, which is acted upon by a cam 214 on the shaft B. The bodies of these ratchet-wheels run between suitable friction-blocks 251 252, which are restrained from rotation on said stud through the action of a suitable spring 253, the stress of which may be regulated as desired by adj usting the collar 254. These ratchet-wheels at their contiguous sides have each a flange, and each flange has an opening of substantially one-half the area of the end of a leg 204, resting with its lower end on both flanges. The openings in these flanges when the loom is started do not register, and the leg is consequently supported by the flanges, and it cannot enter the opening until both register or come exactly opposite each other under the leg. These openings will not register until after the said wheels have been moved a number of times-equal to twenty multiplied by twenty-one, or for four hundred and twentyand as these wheels are moved only at every other pick the openings will not register un-.

til after eight hundred and forty picks of filling have been put into the shed, which number, it will be supposed, will exhaust most of the filling from the filling-carrier used in the shuttle. The number of teeth on these wheels may be varied, so that the product derived from multiplying together the number of their teeth may designate a greater or less number of picks and consequently length of filling put into the shed by the flight of the shuttle through it, and in this way provision may be made for stoppingthe use of a filling-carrier having a longer or shorter length of filling.

Two sets of these ratchet-wheels are shown,

for the reason that in this invention two shuttles are employed, and each shuttle has consequently its own measuring means, and both these measuring means being alike it is unnecessary to particularly describe but one of them herein. 206 and its pair of ratchet-wheels 215 and 216, they being actuated by a pawl 304, also attached to the arm 213. The leg 204 is jointed to an arm 207 of a rock-shaft free to turn in abearing 208 at the end of an arm 210, mounted to turn on a pin 209, said arm having fixed to or movable with it afinger 217. The rockshaft carrying the arm 207 has an oppositelyextended arm 218, to which is connected the bent upper end of the leg 206, so that the descent of either of said legs into the registered openings of either of the flanges on which the legs normally rest will cause the finger 217 to descend.

. The loom-frame has suitably connected with it, as shown in Fig. 7, at its inner side a stand at, having an upright pin 316, (shown by dotted lines,) on which is mounted a rocking hub or shaft 19 provided with two like guidelips (1 said lips receiving and guiding a'drop device 6 having atits lower end a lug f a pin 9 extending through the drop device,

The second leg is marked.

limiting its descent. This drop device has pivoted on it at one side, as at h, a gravitating latch m The loom side sustains (see Fig. ,3) a sta'nd400, in which is mounted the slide-bar 401, having a slot through which is passed the catch h and at its upper end said slide-bar has a projection 403, to be hereinafter described. When the loom is running regularly, the under side of the catch h back of the shoulder 71 rests on'the foot 404 of the stand 400, and the hook at of the catch h occupies a position in and slidesin a plane above the lug f The rock-shaft G in this instance of this invention is shown as utilized to govern the pawls 203 and 304 for actuating the measuring means, said rock-shaft having oppositelyextended arms 300 and. 301, which are connected, respectively, with said pawls by rods 302 303, and inasmuch as the said rock-shaft is movedin unison with the shuttle-box lever employed to raise and lower the shuttle-boxes to put one or the other color in place, said lever also effecting the movement to and fro of the feeder, provided with the extra filling carriers, it follows that only one of said pawls will act at every other beat of the lay, and the particular pawl to operate will depend upon the particular shuttle being used. In

this Way each'measu-ring means will be actuated only while the particular shuttle under its control is being used. The pawl 203 is operated to turn the ratchets 201 and 202 when the lowest shuttle-box of the series is opposite the raceway of the lay, the other pawl 304 being operated when the shuttlebox next above the lowest one of the series is in position opposite the raceway of the lay.

We will herein state that theshuttle-box mechanism shown is capable of caring for a set of three shuttles;but to use it for'two shuttles, as we have herein described, we have only to so modify the makeup of the pattern surface or chain that one or the other of the shafts c or elf employed to move the shuttle-box lever will not be actuated.

Whenever in the operation of the loom a measured or indicated" quantity of filling has been run off or laid into the shed froma particular shuttle, the measuring means cooperating with that shuttle then in operation presents in line the openings hereinbefore referred to made in its two flanges, and a leg before sustainedby said flanges enters the opening, which results in turning the hub of the arm 210'on the stud 209 and lowers the finger 217, it in its descent acting on the beveled edge of the latch 'm and pushing it back, so that the finger passes below the lower end of the catch. This finger will be lowered whichever leg drops and enters an opening, and whichever leg enters the opening it is lifted therefrom instantly, as herein shown, at the same pick in which it entered, this being due to the shape of the lower end of the leg and of the opening, and the quick raising of the leg elevates the finger 217, causing it to strike the lower end of the latch m and lift with it the drop device e putting the lug f connected to its lower end, in the range of movement of the hook n of the catch h said catch turning the rock-shaft I1 and causing the sliderod H which is embraced by the forked arm 0 at the upper end of said rock-shaft, to he slid longitudinally, said movement putting the finger ll, attached thereto, between the short arm of the transferrer 26 and the hunter, so that said bunter meeting the said finger H turns the tra1 1sferrer,as before described. The partial rotation of the rock-shaft b carries the latch on laterally off from the upper side of the finger 217, which lifted the dropwire, so that the drop device may descend and put its lugf out of the range of movement of the catch h. The transferrer having been operated, a suitable spring 59 acts immediately to return the slide-rod into its normal position and return the rock-shaft 1) into its normal position. As the rock-shaft Z1 is returned into its normal position a pin 500 on the latch on meets the convened side of a finger 501, pivoted at 502, said pin by acting against said finger being checked in proper position, so that as the finger descends it will be free from the latch. This latch rises when the drop device is lifted.

Herein, when the filling breaks the loom is stopped through the action of the filling-fork, and the take-up and pattern-surface are also stopped. lVhen the filling is absent from the front of the filling-fork 50 the downturned heel at the opposite end of the fork is caught by the filling-hammer 55, and the filling-fork slide, on which the filling-fork is pivoted, is moved outwardly across the breastbeam. This slide near its outer end has jointed to it a finger g which is pivotally connected with a knock-off lever r pivoted at s on a stand secured to the 100m, said stand having anotched plate a to hold the shipper-handle t the movement of the fillingfork slide, as described, causing the knockoff to push the shipper handle out of its notch, it in its movement cooperating with usual belt-shipper mechanism, (not showng) but said shipper mechanism may be of any of the forms commonly found in Crompton and other looms, as in United States Patent No. 95,092, dated September 21, 1869, and we shall hereinafter designate as the stopping mechanism the shipper-handle and the usual parts to be actuated by it. The upper side of the filling-fork slide has at its end a deep groove a, in which rests at all times the broadened or widened upper end of an arm b fixed to the slide-rod II, no matter what is the position of the said slide-rod, or, in other words, notwithstanding the sliding motion of said rod the said broadened end of the arm b always remains in the notch a Consequently when the filling-fork slide is pushed outwardly,- as described, it, acting on the arm b turns the slide-rod H causing it to turn an attached arm 404, the said arm meeting the projection 403 at the, upper end of the slide 401, thus lifting said slide, so that-when the catch h comes again forward the shoulder 71 will meet a portion of said s1ide,which will stop the movement of the catch 71 and the lever ha,

and consequently will stop further movement of the pattern surface or chain, the spring 71. at such time giving way and letting the lever h move and the slip-joint break away from the pin h. So, also, during the rocking movement of this slide-rod H, the finger H at such time not being in line with the short arm of the transferrer, a finger 0 (see Fig. 4) acts against the upper end of a holdingpawl T employed to engage the ratchet-wheel of the take-up, thus temporarily suspending the operation of the take-up.

The particular construction of the ratchet or other wheels employed in the measuring means and the devices for actuating the measuring means may be variously modified, and instead we may employ as equivalents any usual speed-decreasing mechanism wherein a fast-moving device or wheel actuates another device or wheel at a slower speed, so that the slow-moving device after it has passed over a defined space will cause said slow-moving device to operate suitable mechanism to effect the operation of the filling-changing mechanism.

Referring to Fig. 8, showing a detail of the -measuring means, it will be seen that the lower ends of the legs 204 and 206 are beveled to a rather fine point, and as soon as both openings in the two flanges, with which each leg cooperates, present their edges in alinement the leg will drop, effecting the operation of the transferrer, and, without stopping the movement of the measuring means, the said leg is instantly raised before the lay again comes forward, and so it is impossible to operate the transferrer twice in immediate succession to make two successive changes of bobbin-carrier in the same shuttle.

In our invention we actuate the plurality of measuring means by a plurality of pawls which are practically controlled by a patternsurface, and said pawls are put into and out of position in accordance with the change from one to another shuttle in the series of shifting shuttle-boxes, and these pawls are connected with the shaft G, moved by the movement of the shuttle-boX-shifting lever, in turn controlled as to the time of its movement by the pattern-surface.

The transferrer and its actuating part-s constitute what is herein designated as fillingchanging mechanism, and instead of the particular transferrer and the means shown for actuating it any other suitable or well-known fillin g-changin g mechanism may be employed, and so, also, instead of the particular fillingfeeder any other suitable or well-known device may be employed.

This invention is not limited to the exact measuring means shown nor to the intermediate connections shown between the meas- IIO uring means and the transferrer, for it will be obvious to those skilled in the art that these devices might be variously changed or modified by the exercise only of me'chanica skill and not requiring invention.

This invention is not limited to the particular mechanism shown intermediate the measuring means and the transferrer, and instead of the devices thus far specifically described we may employ mechanism such as shown in Figs. 15 and 16. In these figures the rod H which takes the place of the rod H is merely a rocking rod, and it. has a short arm H on which is pivoted on a horizontally-arranged stud y a finger y, connected at its lower end with a rod 11 in turn connected with one arm of an elbow-lever g y, pivoted at g in a stand "g depending from the breast-beam, the arm y of said lever being extended under the arm 210,.which is fully shown in Fig. 6, and when either of the legs connected with said arm enters the registered openings in the measuring means the said lever g y will be moved to turn the finger y and put it between the short arm 26 of the transferrer and the hunter before described connected with the lay, the finger when so turned causing the transferrer to be worked. 1

As an equivalent for the measuring means we may also use devices such as employed in United States Patents No. 281,195, dated July 10, 1883, and No. 286,206, dated October 9, 1883, letting the drums shown in said patents, which receive the chain or rope to which the weight to be lifted is attached, carry a pattern'chain, as g to act on and lift the lever 11 2 the faster-moving parts in said patents deriving their movement from pawls or other devices actuated by or with the lay. In Fig. 18, showing this third modification, the lever g 3 is reversed from the position shown in Fig. 15.
